Basically the following use case is not handled well:

• Reviewing a build that has quarantined tests
• All tests are magically green
• Ok, so who quarantined these so I can go talk to them to find out more information (are they flakey, or waiting for a fix, did someone forgot to unleash them?). (James Dumay: Fixed in 5.0)
• Flakey? How long have then been green, in time, for how many consecutive builds.

Possible solutions:

• More columns in the summary screen.
  • Who quarantined a test.
  • How long it's been green, time, since build.
• Show the test history page as a pop-up when hovering over the "history" icon.
• Allow the user to provide a reason for quarantining a test.
• Allow quarantining for a certain amount of time (i.e. 1 day, 1 week, etc).
